Abstract

The invention discloses a rubber double-density double-injection product intra-mold foaming and sulfuration molding system and process and belongs to the technical field of rubber product processes. The rubber double-density double-injection product intra-mold foaming and sulfuration molding system comprises a compression molding sulfuration table and two injection machine bases, wherein the two injection machine bases are symmetrically arranged at the two sides of the compression molding sulfuration table. A compression molding sulfuration device is fixed to the compression molding sulfuration table. The two injection machine bases are each fixedly provided with a rubber material injection device. The two rubber material injection devices are arranged oppositely, one is the high-density rubber material injection device, and the other is the low-density rubber material injection device. The compression molding sulfuration device comprises two mold inner cores which are the same in shape and different in specification. By means of the high-density rubber material injection device and the low-density rubber material injection device, two types of plastified rubber materials differentin density are matched with the different mold inner cores and sequentially injected into a mold of the compression molding sulfuration device. Compression molding foaming and sulfuration are conducted on the plastified rubber materials in the mold through the compression molding sulfuration device; injection, foaming and sulfuration of double-density rubber products are completed in the same mold; product transfer among all procedures is avoided; and the production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of rubber products, and in particular relates to an in-mold foaming vulcanization molding system for rubber double-density double-injection products and a molding process thereof. Background technique [0002] In general, substances that make rubber and other polymer materials porous can be used as foaming agents. Physical foaming is a common rubber foaming process. The principle is to dissolve the foaming agent in the high polymer. When the pressure of the system decreases or rises steadily, it turns into a gas to make the high polymer volume expand and boil and foam. The special equipment for foaming (continuous foaming machine) has very strict requirements for foaming equipment, which is extremely inconvenient to use and increases the cost of equipment. [0003] The existing physical foaming process is to use a continuous foaming machine for rubber foaming—injection or extrusion molding—vulcanization—fin...
